For HTE, the hydrogen electrode of the stack was fed with H2 0.5L/min and steam(2.24L/min, 1atm, 298K) where H2 was used as protective gas me- dium. The stack was subjected to HTE at 800° C (1,472° Fahrenheit) in the mode of solid oxide elec- trolyzer cell (SOEC) with a constant current of 4 A.
The stack exhibited a stable performance for more than 900h without any degradation. The electro- lysis conversion rate was calculated 73.5% by measuring the input and output steam mass of the stack, and the hydrogen production rate was over 98.7NL/h. It is thus indicated the HTE using SOEC is effective to produce hydrogen at a high conversion efficiency and a reasonable production rate, and is of potential to scale up to a large-scale hydrogen production.

CEA-Leti has developed an ultra-sensitive infrared detection matrix that can measure infrared waves within the range of 8 to 10 µm with a resolution of a thousandth degree Kelvin. This result was achie- ved by combining a detection matrix with a specific circuit for both reading and digitally converting the data. SOFRADIR produces the technology.
SOFRADIR develops and manufactures advanced infrared detectors for military, space and commer- cial applications. The company specializes in cooled IR detectors based on a sophisticated high perfor- mance technology, Mercury Telluride Cadmium (MCT).
Professor Kostya (Ken) Ostrikov of the Plasma Na- noscience Centre Australia, CSIRO Materials Sci- ence and Engineering, has highlighted, in Journal of Physics D: Applied Physics, the unique potential of plasma nanoscience to control energy and matter at fundamental levels to produce cost-effective, en- vironmentally and human health friendly nanoscale materials for applications in virtually any area of hu- man activity. In particular, Ostrikov points out the ability of plasma to synthesise carbon nanotubes.

At end of March 2011, the Department of Light- weight Structures and Polymer Technology (SLK), Chemnitz University of Technology Chemnitz, Germany, and the affiliated Cetex Institute presen- ted exhibits from their latest research at JEC Com- posites Show in Paris. SLK demonstrated a wind power rotor blade model with integrated sensors.
